How do they come? Does it need assembly..it looks big for a box. Also can you put it into a big suitcase. I think I would want my friend coming the states to bring it for me.

The only assembly it needs is unfolding and popping the pieces in place. It is really simple in my experience (I've built two so far). It would have to be a really big suitcase but you could probably do it. We had big suitcases that would definitely fit one. Or if you traveled with a duffel bag it would fit in a large duffel.

Ours came in the paper a couple weeks ago. I have read that they aren't in stores this year but that the cashiers are supposed to have a scan sheet to use them at checkout of you didn't get one...maybe call your target and ask them?
